Product features

1. Simple structure and high reliability.

No complex control system such as inverter is required, low failure rate and low maintenance cost. The mechanical 

components are mature in design, with strong long-term operation stability, suitable for high-load continuous operation.

2. Low initial investment cost.

Compared with variable frequency air compressor, the inverter and complex electronic control system are omitted,

and the equipment procurement cost is more competitive.

3. High efficiency and energy saving (under specific working conditions).

Under the condition of stable load rate (close to 100%), the energy efficiency performance is excellent, which is suitable 

for scenes with small fluctuations in gas demand.

4. Convenient maintenance.

The maintenance technology of fixed speed motors and traditional control systems is popular, spare parts replacement 

is simple, and technical support is extensive.

5. Clear applicable scenarios.

It is suitable for industrial scenarios where the gas consumption is stable and does not require frequent adjustments

(such as continuous gas supply to production lines, supporting fixed equipment, etc.).
